Build a house or get one off the gallery?

I don't build often since I'm so fussy it takes me a ridiculously long time to complete anything and I'm just too lazy. I must admit though that when I do build something entirely myself that it gives me a nice feeling of satisfaction, so I do prefer it. I mostly use my own and Maxis builds in my main save. However, in other saves, I usually go to the gallery first, find something close to what I want and then edit it to suit my household.
